No really, who is the asshole here?

Opinions:
Me or the other?

Neighbor leaves cat out all day. It’s low 20’s, windy and blowing snow. I am talking about all day, since before 10am and it’s now 9pm. Still not home.

I just spent about an hour putting together a weird little shelter on the porch, bringing out food and water, trying to call the persons number and when not getting a call back, calling animal rescue to find out what the cat’s needs were likely to be. (Turns out there is no law saying you have to have a shelter for your outdoor cat. That sucks balls). Walking over to the “friend/SO’s” house to see if they were home and could let the cat in, NOT.
The cat was crying and climbing up the screen door!
Oh and also tried to call the neighbor who cat sits it.

But really, am I just totally a control freak who is so overstepping here?

Edit: The cat sitter called and gave me the authority and a code to let her in. So I grabbed all my crazy stuff and took it back home. Now I have my yard-sale cat carrier all scrubbed out and nice for my cats, so that is bonus, to get me off my ass to do that.
